Serial No. 5C/3,753.

la. rlihe pressing head 11 is movable toward and from a lined pressing element or buck 15 to close and open the press. The huclr 15 is supported hv a ricchi@ which is mounted on the pressing machine trame 1li.

rlhe yole 12 is pivotally connected at 2O to a driven lini The driven linlr 21 is pivotall7 connected at 3 to spaced link memhers 25 which. ely secured to a pinion shaft 2G. "1' 23 is rigidly secured to the pii n shaiit and the pinion shaft 26 is rotaraolv mounted in a voire 30 which is formed on the end ot a hell crank 32. The hell c r is pivotally mounted on shaft 3d w n is secured tothe pressing machine trame 14C. Y

A driver lever is pivotally mounted on the shaft 3d and is provided with a slot 36 near one end thereof. rvEhe driver lever 35 is provided with a gear segment 38 at one end and the pinion 23 meshes with the teeth of gear segment 38. A second driver lever 39 is mounted on the shaft 34 and is identical in construction with the driver lever 35, with the exception that it does not have an end portion witl the gear segment 38 formed thereon.V The link members 25 operate in the slots 33 of the driver levers 35 and 39, see Figures 3 and 4. rlhe lower end of the slots 36, designated as 40, provides a stop to limit the downward movement of the links 25 in the slots 36.

g rlfhe driver levers 35 and 39 are secured together at their forward ends by pins 42 and fill. The lower end oi a piston rod l5 is pivottall7 mounted on the pin dei and a connecting member i7 forms a pivotal connection between the pin 4:2 and a spring` 50.

rthe springis connected at its upper nd at 51 with the pressing machine trame e' and normally holds the driver levers 35 nd 39 in npraised position, as shown in 1Eigure 1. il spring 52 which is connected to the yoke. 12 one end and to the pressing machine trame 14 at the other end, normally;T holds the press in open position. fr fluid motor 53 is oscillatahly mounted at 55 on the pressing; machine trame 1li and operation of the iiuid motor 53 moves the piston rod 45 to actuate the driving levers 35 and 39 to rock push button 94 operates a bell crank 95 which transmits motion of the push button 94 to the rocker arm 86 to Voperate the valves 81 and 82 in the valve casing 79. A spring 96 holds the bell crank 95 and push button 94 in normal inoperative position.

The valve casing 78 contains an exhaust valve 102 which is provided With a valve stem 105 extending through the end of the valve casing 78. A rocher arm 106 contacts With the end of the valve stem 105 to move the exhaust valve 102 into closed position. The rocker arm 106 is pivotally mounted at 107 on a bracket extending from the valve casing 78. A diaphragm chamber 109, formed on the lower side ofthe valve casing 78, contains a diaphragm 110. A plunger 112 extends through the end of the diaphragm chamber 109 and when pressure is applied behind the diaphragm 110, the

vplunger 112 will be operated to move the rocher arm 106 to close the exhaust valve 102, or hold the exhaust valve 102 in closed position. A push button 114 operates a bell crank 115 which transmits motion from the push button 114 to the rocher arm 106 to 0perate the valve 102 in the valve casing 78. A spring 116 holds the bell crank 115 and push button 114 in normal inoperative position. The valve casing 79 is connected with a suitable source of Working fluid by a fluid supply line 120. When the push button 94 is operated to open the intale valve 81 and close the exhaust valve 82, Working fluid Will oiv `from the fluid supply line 120, around the open intake valve 81, through the valve casing 79, branch pipe 76, and pipe 74 to the cylinder 70 to operate the fluid motor to close the press, as previously described. lt is necessary that the push button 114 be operated to close the exhaust valve 102, since if this valve 102 is left open, VWorking' fluid from the pipe 74 may escape through the branch pipe 75 and past the open exhaust valve 102, thus preventing pressure from building up in the pipe 74v and cylinder 70 to operate the motor 53. This control mechanism for supplying Working fluid to the motor 53 is of the conventional two-hand control type and forms no part of the present invention.

rl`he valves in the valve casings 78 and 79 are locked in operated position by conventional means such as a port opening 122 which is located in the Wall of the cylinder 7 0 at a point near the end of the stroke of the piston 71 so that the piston 71 will un cover the port opening 122 Whenthe press moves into closed position. When the piston 71 uncovers the port 122, Working fluid will flow into the chamber 125 and through the pipe 126 and pipes 128 and 129 to the diaphragm chambers 109 and 89, respectively, to act-nate the diaphragms therein and lock the valves in the valve casings 78 and 79, respectively, in operated position.

The bell crank 60 is pivotally mounted at on the pressing machine frame 14. The spring 62 normally holds the bell cranl 60 in contact with a stop lug 136 which is formed on the pressing` machine frame 14. A diaphragm chamber 138 is mounted on the pressing machine frame 14 and contains a diaphragm 140. The diaphragm 140 open ates a plunger 142 which extends through the end of the diaphragm chamber 138 and contacts with the upper end of the bell crank 60. A pipe 144 connects the pipe 129 with the diaphragm chamber 138 and When the piston 71 uncovers the port opening 122 to supply Working fluid through the pipe 129 to the diaphragm chamber 89, as previously described, Worlring fluid will also pass through the pipe 144 to actuate the diaphragm 140 in the diaphragm chamber 138. lVhen the diaphragm 140 is thus actuated, the plunger 142 Will rock the bell crank 60 about the pivotal connection 135 and raise the latch 59 out of contact with the pin 58, thus releasing the bell crank 32. Since the diaphragm 140 is operated by Working fluid which escapes through the port opening 122, and since the port opening 122 will not be uncovered by `the piston 71 until the press has reached closed position, it is obvious that the pin 58 will always be released by the latch 59 at the proper time during the closing of the press.

Means are provided to open the press by relieving the pressure in the diaphragm chambers 89 and 109. These means include a handle which opens an exhaust valve 151 which is normally held closed by a spring 153. The exhaust valve 151 is located in a valve casing 154 which is connected by pipe .155 with the pipe 126 through Which Worling fluid is supplied to the diaphragm chambers 89 and 109.

Operation of the mechanism is as fol-h loivs With the press opened and the parts in the positions shown in Figure 1, the operator will depress the push buttons 94 and 114 to operate the valves in the valve casings 79 and 78, respectively. VVOrking fluid from the fluid supply line 120 Will flow around the open intake valve 81, through the valve casing 79, and branch pipe 76 to the pipe 74. The exhaust valve 102 being closed, pressure Will build up in the pipe 74, branch pipe 75, and cylinder 70 to operate the piston 71 and piston rod 45 of the fluid motor 53. The piston rod 45 Will move downwardly and rock the driver levers 35 and 39 in a clockwise direction about the shaft 34. The gear segment 38 on the driver lever 35 will move upwardly, about the shaft 34 as a center, and Will rotate the pinion 28 in a clockwise direction since the pinion is held against movelfxlhen the presor 53 is hus reduced, l 'in-ove 'he press n heck in eli-press Wil io' and 2 che elves 102 and 82. n the luid i ust "e shaft 34 by the Valve casings Z8 and 79, and past the open e pin 58 of the hell enhq he pinion shaft 2 is sur he gear segment 3S Wil'y a link inem iS of th .il
